[PHP] How are variables called in current php?

[Wei Wang]

hi, all,

I have a piece of code stuck at the point of "if (($REQUEST_METHOD=='post'))". 
"var_dump($REQUEST_METHOD);" shows that the variable doesn't exist. 
Since I grabbed the code from a 2001 update, is there any chance that this is already 
obsolete? I checked the documentation but didn't find anything relevant.
Any advice would be highly appreciated. ;-)



The following is the complete code that I got stuck at


if (($REQUEST_METHOD=='post')) {

////////////////////////////////
// This loop removed "dangerous" characters from the posted data
// and puts backslashes in front of characters that might cause
// problems in the database.
////////////////////////////////
  for(reset($HTTP_POST_VARS);
            $key=key($HTTP_POST_VARS);
            next($HTTP_POST_VARS)) {
    $this = addslashes($HTTP_POST_VARS[$key]);
    $this = strtr($this, ">", " ");
    $this = strtr($this, "<", " ");
    $this = strtr($this, "|", " ");
    $$key = $this;
  }
else
{ print ('Boo, I never got executed'); }//apparently the script never make it to this 
point

And add appriopriate
           assigments at the top of your script.
